New York - JANE and Greg Hills were visiting New York City when they grabbed a drink in the lobby bar of the Dream Downtown, a boutique hotel in Chelsea. As the full room pulsed with music and guests, the couple had an epiphany: Dream should run their new hotel in Durham, North Carolina.

"We had been talking to all the major brands, but we wanted someone innovative, creative and entrepreneurial," Ms Hills said of Dream, a relatively small company that operates 16 hotels. "The banks wanted us to go with someone more well-known, but Dream was the right match for us." The result is Unscripted Durham, a hotel that will have its soft opening this month and the official opening in July in the centre of a revitalising downtown. With its rooftop pool and five restaurants on the premises - a considerable number given that there are just 74 rooms - it is the latest in a wave of new boutique hotels in the nation's smaller cities.

The Trump Organisation, for example, recently announced plans for Scion, a boutique brand that will open its first location in Cleveland, Mississippi. Industry giants like Marriott and Hilton have also aggressively moved into boutique hotels, sometimes called lifestyle hotels. The hotels usually highlight a property's unusual architecture or history, have no more than a few dozen rooms and offer special guest services or amenities.

"In this industry, when one person thinks it is a good idea, everyone joins in," said Jan Freitag, a senior vice president at STR, a hotel research firm. "The industry is firing on all cylinders on the supply side." While hotel expansion is fairly typical in big cities when the economy is growing - New York leads the way with 15,470 rooms under construction - it is less common in smaller areas. In Durham, for example, the number of available rooms grew 5.7 per cent in 2016, more than triple the national average, according to STR data. In Cleveland, the number of rooms surged 5.8 per cent, while the Albany area of New York had a 5.3 per cent increase.

Of all the rooms under construction now, about a quarter are in boutique hotels, according to data from Tourism Economics, a company that forecasts travel trends.

The boutique hotel push is driven by travellers' increasing desire for "genuine" experiences, said Bjorn Hanson, a professor at the Jonathan Tisch Centre for Hospitality and Tourism at New York University. Many travellers want something fresh and different, instead of the standardisation of the large hotel brands.

Expanding beyond large areas such as New York and Los Angeles largely comes down to cost. In New York, for instance, construction and labour costs have outstripped increases in room rates, making it difficult to generate attractive returns on investment.

Building a luxury hotel in New York costs about US$1.5 million per room, Dr Hanson said, compared with just US$500,000 in many smaller cities.

"Costs have increased dramatically in gateway markets, and many brands need to continue growing, so they are looking outside the typical cities," he added.

Many companies like what they see in smaller cities. Downtowns like Manchester, New Hampshire, and Youngstown, Ohio, are being revitalised as young adults seek out more urban lifestyles, tech hubs pop up and companies relocate there.

Websites like TripAdvisor also make it easier for boutique hotels to market their rooms to guests. Their reviews and photographs give guests greater comfort in booking these boutique properties, according to Aran Ryan, the director of lodging analytics at Tourism Economics.

"There is also more value in staying at boutique hotels than before, since guests can post their distinctive experiences on Instagram or Facebook," he said.

With so many new rooms, there are some concerns about oversupply. For instance, the growth in a common industry metric, revenue per available room, is expected to slow this year. After rising 3.2 per cent last year, it is expected to grow 2.2 per cent this year, according to Mr Ryan.

The new level of competition is playing out in Durham. Across the street from the Unscripted Durham is another boutique hotel, 21c Museum Hotel, which has historic architecture and a rotating collection of artwork on display. Demand in the city, with more than 252,000 people, rose 5.3 per cent in 2016, almost matching the increase in rooms.

The Dream Hotel Group hopes Unscripted Durham will be the first in a string of Unscripted hotels. A second property is scheduled to open in Flower Mound, Texas, in 2019, and discussions are ongoing for other locations.

"It used to be that boutique hotels worked in the coastal cities like New York, but now the centre of the country is also looking toward this lifestyle," said Jay Stein, the chief executive of the Dream Hotel Group. "We are excited to become part of that." NYTIMES
